US Sen. Murray's Office Evacuated Due To Envelope

Posted: Updated:

TACOMA, Wash. (AP) - The district office of U.S. Sen. Patty Murray in Tacoma, Wash., has been evacuated after a staffer found a suspicious envelope in the mail.

Tacoma Police Det. Gretchen Aguirre says the letter-sized envelope contains a sand-like substance and the staff member was concerned about the return address. Aguirre says nothing has come out of the envelope and she wasn't sure what about the return address was suspicious.

Murray was not in the office on Thursday when her staff called police. Aguirre says fire officials did a preliminary check and then called the postal service to pick it up. She says the envelope had already gone through the post office's regular hazardous materials screening.

A call to Murray's Washington, D.C., office seeking comment was not immediately returned.
